Which chamber of the heart pumps oxygenated blood to the body through the aorta?

Explanation:
Pumping oxygenated blood to the body through the aorta is the job of the left ventricle. The left ventricle has a thick muscular wall to generate the high pressure needed to propel blood into the aorta, which then distributes it to every body tissue. Blood becomes oxygenated in the lungs and returns to the heart, filling the left atrium, then moves into the left ventricle before being sent into the aorta. By contrast, the right ventricle moves blood to the lungs via the pulmonary artery, not to the body, and the atria simply receive blood and pass it to the ventricles.
